Go (Golang)

Overview​

Go from Google emphasizes simple syntax, fast compile times, static typing, built-in concurrency (goroutines, channels), and a single static binary deployment story. It is widely used for CLIs, network services, Kubernetes ecosystem tools, and cloud infrastructure.

Key concepts​

  • Goroutines — Lightweight threads scheduled by the runtime.
  • Channels — Communicate sequential processes (CSP style).
  • Interfaces — Implicit satisfaction; small interface composition.
  • Modules — go.mod / go.sum dependency management.
  • Error handling — Explicit if err != nil (with helper patterns).

Goroutine + channel (conceptual)​

Sample: HTTP server​

package main

import (
  "fmt"
  "net/http"
)

func main() {
  http.HandleFunc("/api/health", func(w http.ResponseWriter, _ *http.Request) {
    fmt.Fprintf(w, `{"ok":true}`)
  })
  _ = http.ListenAndServe(":8080", nil)
}
